Communicated by our good friend Archibald Menzies, Esq., who found it in the Island of 

 Owyhee. It was marked by that gentleman, iC Asplenium, nova species ;" and we entirely agree with 



him in its being 



Its 



ally 



questionably, Asplenium monanthemum of Linnseus, and 



( 



of Smith Icones, Tab. 73, an inhabitant of the Cape of Good Hope ; and as we know, from spe- 

 cimens we have received from the Rev. R. T. Lowe, of Madeira also. That plant is always much 



broader in its circumscripti 



the middle, more attenuated at the base and at the extremity 



having the pinnae of a more delicate texture, much longer and narrower, more disposed to be 

 caniculated in the upper margin at the base, and with fewer sori, and those (mostly indeed solitary) 



confined to the lower side of the pinna. 



Sprengel describes the Aspl. monanthemum as an inhabitant of New Spain, Martinique, Peru, &c. ; 

 and he makes the Asplenium nanum of Willdenow to be synonymous with it. Now this latter plant 

 is indeed an inhabitant of Martinique, and is figured in Plumier ; but, as that figure shows, it is 

 quite a different species from A. monanthemum.
